T 0 aZZ whom it may concern:

Be it known that I, WILLIAM G. BOUGH- TON, a citizen of the United States. residing at Frostburg, county of Alleghany, State of Maryland, have invented anew and useful Inlproveinent in Wagon-Jacks, of which the following is a specification.

The object of my inventionis to form a simple compact Wagon-jack which can be operated quickly and easily by the hand for rais ing wagons, carriages, 850., when this is nec essary for the purpose of removing the wheels, or for any other purpose. I attain these objects by the mechanism illustrated in the accompanying drawings, in which both Figures 1 and 2 represent side views.

A,Fig. 1,is a standard with the guides a a attached; B, a sliding post which is held in a vertical position by the guidesac, and Oalever with a broad triangular head which is connected 1 with the sliding post B by the strap and pin b, and to the top of the standard A by the link D, which is composed of the rods and pins (1 d.

The jack is made proportionately strong to the work required, and is of suficient height to allow the top of the sliding post B to be placed beneath the axles of ordinary wagons.

In raising an axle for the purpose of removing a wheel, the jack is placed in a position near the wheel with the top of the sliding post B directly under the axle, the link D serving as a fulcrum. The lever O is then pressed downward by the hand, which elevates the sliding post and with it the axle. When the lever is pressed downward,the top of the link D is forced toward the sliding post B until the square part of the head of the lever comes in contact with the sliding post, as shown in the side view in Fig. 2, which represents the slide-post elevated and the lever down in its lowest position. The weight pressing upon 7 the pin 1), and falling upon the top of the link
